IMPROVEMENT m STUMP-PLOWS.

Specification forming part of Letters Patent'No. 199,930, dated July 10,1877; application filed May 5, 1877.

To all whom z'tmay concern Be itknown that I, WASHINGTON PAINTER, of Albion, in the county of Edwards and State of Illinois, have invented a new and Improved Stump-Plow, of which the following is a specification:

Figure l is a side elevation of my improved plow. Fig. 2 is a detail View of a plate for holding the colter. Fig. 3 is a top View of a portion of the beam, showing the plate for holding the colter. Fig. 4 is a vertical section of the plow-standard.

Similar letters of referencc indicate corresponding parts.

The object of my invention is to provide a stump-plow that may be used in rough newlycleared timber-land, that will readily cut the smaller roots, and will jump over or escape the larger roots.

In the drawing, A is the beam of the plow, having the ordinary handles and clevis, and B is a oolter of peculiar form, which is held in position by a plate, a, of rhomboidal form, having lugs b, and is clamped to thebeam by the bar 0 and bolts d. The plate a is further secured to the beam A by bolts 0, and by letting it into the side of the beam. The corners of the said plate are disposed so as to ofl'er the greatest resistance to the leverage of the colter.

The colter B is bent at f, and its cutting edge, which is convex in the direction of its length, is pitched forward.

0 is an iron standard that is fitted to the back of the mold-board, and is made hollow, being open at back, and is provided with a cross-piece, g, and cross-bar h. This standard is secured to the plow-beam by the bolts t j k. The bolt t passes through the beam and through the head of the standard. The bolt j passes down through the beam and crosspiece 9, and the bolt it passes diagonally downwardthrough the beam, through the front of the standard, and through the cross-bar h.

The mold-board D is secured to the standard by means of bolts, in the usual way.

The standard 0 is offset, so that the upper portion of it is even with the outer surface of the mold-board.

This plow readily cuts the small roots, and by a slight movement of the handles can be made to escape large roots or obstructions.

Having thus described myinvention,I claim as new and desire to secure by Letters Patent- The standard 0, having the cross-piece g andcrossbar h, and adapted to the mold-board D, substantially as shown and described.

WASHINGTON PAINTER.
